From Brian Horton, West Launceston, Tasmania, Australia
I was horrified to read of stop lights in offices warning staff not to interrupt colleagues who are typing at high speed, and a green light encouraging them to talk when typing slows (6 May, p 9).
When I am typing at high speed, I am doing routine stuff that can easily be stopped and restarted, but a slower speed means I need to think carefully and should be left alone. So I was relieved to read of the benefits of daydreaming for creativity (20 May, p 26). My co-workers know that if I am staring blankly out of the window, I am solving some complex problem and must not be disturbed. Maybe I should just swap those red and green lights.
